COUNTERMEASURE METHOD FOR A MOBILE TRACKING DEVICE
First Claim
Patent Images
1. A method for keeping a mobile tracking device away from an asset, the mobile tracking device having a seeker head which is directed at an asset due to the infrared energy radiated by the asset, the method comprising the steps of:
- directing an output of a continuous wave laser at the seeker head along a first direction of travel of the mobile tracking device, the output of the continuous wave laser being infrared energy; and
propagating the infrared energy from the continuous wave laser into the seeker head of the mobile tracking device to generate at least one localized source within the mobile tracking device and within a field of view of the mobile tracking device which indicates a second direction of travel for the mobile tracking device.

Abstract
A countermeasure method for directing a mobile tracking device away from an asset is provided. The countermeasure method includes directing the output of a continuous wave laser source at a seeker head of the mobile tracking device. The countermeasure method causes the generation of localized sources within the mobile tracking device and confuses the mobile tracking device as to the true location of the asset.

4. A method for keeping a mobile tracking device away from an asset, the mobile tracking device having a seeker head which is directed at an asset due to the infrared energy radiated by the asset, the method comprising the steps of:
-
activating a continuous wave laser; directing a beam of infrared energy from the continuous wave laser at the mobile tracking device, wherein the beam of infrared energy causes the mobile tracking device to explode in a first separation band;
causes components of the mobile tracking device to become inoperative in a second separation band, the second separation band corresponding to distances longer than first separation band; and
causes localized internal sources within the seeker head which cause the mobile tracking device to alter its direction of travel away from the asset in a third separation band, the third separation band corresponding to distances longer than the second separation band.

5. A method for keeping a mobile tracking device away from an asset, the mobile tracking device having a seeker head which is directed at an asset due to the infrared energy radiated by the asset, the method comprising the steps of:
-
detecting the location of a mobile tracking device with a first detection system having a wide field of view; passing the coordinates of the mobile tracking device to a second detection system having a narrow field of view; continuing to monitor the location of the mobile tracking device with the first tracking system until the second tracking system locks onto the position of the mobile tracking device; and directing optical energy from a continuous wave laser at the mobile tracking device, the optical energy causing the mobile tracking device to alter its direction of travel. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
